Abstract:
The rationality and stability of operational inner profile is of great importance to smooth operation for blast furnace, which can be hardly measured directly. To realize online monitoring, a wireless digital measurement system for water temperature difference of cooling staves, with high precision and stability, is developed firstly. Based on the primary detecting data, three dimensional heat transfer models of cooling stave walls are built. Then, by means of the inverse problem, the thickness of brick or skull, the skull drop frequency, the hot face temperature and the distribution of peripheral gas flow in blast furnace are calculated and displayed. With the application of this model in some blast furnaces in China, rational management standards of furnace wall are built, which is beneficial for effectively controlling the furnace operation. Also, the model can reflect the change of root position of cohesive zone caused by raw materials change.
